Our World: Propulsion Systems

[jessyjessy4]

love the video man

[lightfdar]

If you guys want real science check project Icarus or u can wait another 200 year with Nasa garbage

[lightfdar]

this is sad no real work done since 1970 but you guys always get more money <_< Nasa is the government telling you not to go into deep space cause there afraid of what you guys might find :(

[exmarine66]

Nuclear, ion and laser. 'Nuff said.

[masterdelrap]

NUCLEAR IS ONLY USE FOR SPACE TRAVEL NOT FOR LAUNCH

[jordanpasek]

Chuck Norris powered rocket!!!

[AnarchyRealmz]

other than the VASIMR rockets human propulsion SUCKS. We need antigrav! look into scalar physics and get us one of those F.T.L resistance avoiding systems that the aliens use.

[sunnyXsideXcyanide]

this was never a reading rainbow movie i watched in class.

[posro1988]

1:21 nucular LOL

[herehavealook]

I like the bit at the end, boing boingy boingdy boingedy boingy and thats just goatee man walking off!

[calvingmail]

Finally they will know to use the power of fat.....100 Chinese slit eyed dipshits will eat egg noodles and dumplings and fart their way to mars

[Shuttheheckup735]

@calvingmail Lol you really are sick, posting a racist comment on a video meant for children, you can go suck a big, green, rod of uranium and die of cancer caused by radiation to the mouth. have a nice day :)

[helscreamer]

@calvingmail someone's jealous that they failed skule... lol

[calvingmail]

@helscreamer

who me? 4.0, MS in Computer Science....does that help?

[helscreamer]

@calvingmail haha, okay, so you're just racist...

[pcjwss]

the fat guy seems to have a natural wobble as he speaks.

[Ja2so4]

Propaganda!!!!!! But kind of cute

[Ja2so4]

Propaganda!!!!!!

[glennirish]

Weird

[GAMA3000]

creepy video...

[dt28469]

Earl's friend Randy here sucks at acting.

[scificorner]

Rise your hand if you wanna go into deep space with a nuke tight to your as*...

[mithras1001]

this was the funniest thing ive seen in years

[nootaramus]

the alien ships use anti gravity drives. this is achieved by using mercury or similar elements ( some not found on earth) and then these elements are charged with electrons- positive and negative to achieve flight and propulsion. the elctron charges push the vehicle upward by negating gravity and then the propulsion si achieved by guiding the vehicle "downhill" and shifting the charged fluids in the direction you want to go.

[scificorner]

@nootaramus Doctor`s do not recommended using the so called anti gravity drives in space, you might bounce like a pinball ball crushing with every field you find on your way, on earth they are quite effective reacting only with one field. Anti-Matter would also be a problem, to instable..The best way to travel thought space is not going into space at all...

[Budovec1]

No way man, Anti-matter propulsion is the way to go...

[QuantumCarl]

I feel like when she asks him anything, he should hit her. Just the way she says it, it's like "OH YEAH UH HUH SURE NICE GOATEE YOU LOSER LOLOLOL" :P

[HemiHead66]

Why don't you just bring out some of that Alien technology you're sitting on?.

[cookiemaster1234]

or maybe just use a magnetic tube and the maglev train principle to launch a rocket up?

[tlucentefl]

"nuculer"...Sorry, im not aware of this method of space travel. Perhaps it's when you compress a can of Bud Light and it goes supercritical :D?

[ssslawek]

now i know more. Doesn't matter what propulsion system you are using, chemical, electromagnetic or electrostatic, there is always fire blowing from the pipe...

[KirkMcLoren]

@ssslawek

yes, all systems except wheeled systems produce motion by ejecting something

primitive isnt it?

[Puzzoozoo]

National minded attitudes like this will have to be eradicated if we are to go anywhere.

[yoguely]

Tree House Detectives! :D

[yoguely]

Bianca Baker!! :D

[ihmesekoilua]

damn that is one annoying-sounding kid.

[reinrod01]

back when nasa was still trying to inspire kids to go into STEM feilds.

[EuroSon99]

This video debate seems to be prepared and remembered in advance. Who knew. lol

[Sixalienasa]

This is NASA for Kids. Kids will believe anything.

[docatomics]

...don't kids ask the darnest things !

[KKM121]

"Nuclear" NOT "Nuculer".

Please, you are from NASA.

[daro2096]

Wow! Obviously scripted. And them two are bad actors. It looked like they were reading off cue cards and that guy could do with losing some weight, hit the gym fat boy.

[KohnanTB]

It would be infinitely more tolerable to hear this girl asking planted questions if she miraculously came up with "What is nuclear thermal rocket propulsion?" or "Why do we cling like apes to outdated chemical rocket propulsion over nuclear?"

"Well, little girl, too many government jobs are at stake so screw you and your space aspirations!"

[twk373]

Chemical rockets suck!

Nuclear rockets rule!

[sjmeerkees]

@twk373

you suck balls. how bout that.

[twk373]

@sjmeerkees

Whatever gets you off, dude.

[sjmeerkees]

@twk373

yes ! i knew it.

[Qasimbajwaa]

@twk373 nuclear=chemical lol

[twk373]

@Qasimbajwaa

Chemical reactions move electrons. Nuclear reactions move protons and neutrons. Nuclear reactions are vastly more energetic, and thus would allow us to build vastly better rockets--rockets powerful enough to easily put a colony on the moon. Or mars. Please take a class in physics. <3 Unfortunately, hippies and other clueless, neo-luddite pansies are terrified of nuclear power in much the same way that cavemen cowered in fear of fire. Radiation? OH NOES.

[Qasimbajwaa]

@twk373 Nuclear chemistry is a branch OF chemistry thats all I was saying calm down dont be so arrogant you sound like an arse especially cause you're babbling on about something I already know

[twk373]

@Qasimbajwaa

Sorry, I am arrogant. So naturally that's how I come across. Anyway, if you know anything about rockets, you know that nuclear rockets rule and chemical rockets suck. Thus, I deduce that you are either lying or simply being an "arse." <3

[Qasimbajwaa]

@twk373 look up the definition of pedantic

[twk373]

@Qasimbajwaa

Look up the definition of nuclear rocket.

[Qasimbajwaa]

@twk373 we've already been over this i know what a nuclear "pulse" rocket is

[twk373]

@Qasimbajwaa

Then you agree that chemical rockets suck, and nuclear rockets rule.

[Qasimbajwaa]

@twk373 i wouldn't say that chemical rockets suck considering the fact that they have been in use for many years and have played a vital role in the development of the space program today...i admit that nuclear rockets are cool but are completely impractical because the amount of acceleration produces over 300 Gs which would tear the human body apart plus the chances of damage the pulse rocket could do to satellites is just too much

[twk373]

@Qasimbajwaa

Second, f=ma. The entire point of an orion drive is to design massive spaceships with massive payloads, to go with the massive thrust. Leaving your passengers with a sensible level of acceleration. All of the major technical limitations to nuclear pulsed propulsion have already been overcome, the only difficulties are political. OH NOES KNEWCYULAR BOMBZ IN SPACE MUTANT RADIATION ARMAGEDDON. Damn hippies.

[Qasimbajwaa]

@twk373 look at the wiki for pulse rockets and you will see entire sections devoted to problems with this design and IF you made a rocket that big you would need ENORMOUS chemical rockets to get you out of the Earth's atmosphere and away from the planet before you can start detonating nukes in space and we don't have anything which can lift that much weight even if they got into space they would pose a threat to satellites because nukes give off EMP when they detonate)

[twk373]

@Qasimbajwaa

Actually, the nuclear rocket would be used to get into orbit, too. That's part of the point.

[Qasimbajwaa]

@twk373 dont be silly nuclear ordinance detonated in the atmosphere would blast apart the ozone and put out power in practically the entire US if it were used in the atmosphere

[twk373]

@Qasimbajwaa

LOL. Stop watching movies, hippie.

[Qasimbajwaa]

@twk373 its simple fact and if all you care about is huge explosions and what not then you're the ignorant one

[twk373]

@Qasimbajwaa

The only thing standing between us and cheap space travel is ignorant hippie-luddite reactionaries.

[Qasimbajwaa]

@twk373 building nukes is NOT cheap.

[twk373]

@Qasimbajwaa

That's because we don't have an industry devoted to it.

[Qasimbajwaa]

@twk373 because people a while back had this exact same conversation and came to a decision trust me those men are way smarter than you or me they know what they are doing

[twk373]

@Qasimbajwaa

First, the only reason chem propulsion has played a "vital" role in the space program is because nuclear propulsion is all but banned. Had project orion become a reality, we would have colonies on mars and the moon, and space travel would be cheap enough for ordinary people. The reason the space program's accomplishments are so anemic by comparison is that chemical propulsion dictates super-expensive, super-tiny payloads.

[Qasimbajwaa]

@twk373 its banned for a reason my friend and there is no way that we would have colonies on the moon and mars there are hundreds of other issues with those projects that we have absolutely no solution for...plus pulse rockets would require so much uranium enrichment (which is a diplomatic issue in itself) that there is no way that the IAEA would approve of it because it would just be a mask for nations developing nuclear weapons (which is basically what a pulse rocket is anyways)

[twk373]

@Qasimbajwaa

I guess you weren't paying attention when I said, "OH NOES KNEWCYULAR BOMBZ IN SPACE MUTANT RADIATION ARMAGEDDON. Damn hippies." Are you a damn hippie? See, the only people interested in nuclear warfare are a few muslim extremists. There is nothing irrationally dangerous about building nuclear bombs to propel spaceships--unless you're a reactionary whose knowledge of nuclear power is limited to Hollywood's embarrassing theatrics.

[andre20041997]

@twk373 no, plasma rockets rule



[twk373]

@andre20041997

Plasma rockets are nuclear.

[twk373]

Dude, geeks are not known for their acting abilities.

Lay off the guy. ;-)

[TheReasonWhyGuy]

"nululer" says the guy in the video, just like bush.

The word is spelled nuclear, like new clear.

[nothke]

oh my god. Soooo scripted

[talent245]

Great video!!!!
